NHTSA Complaint #11683892 — 2020 CHEVROLET BOLT EV

High-voltage battery failure left Bolt EV immobilized after recall fix: Our 2020 Chevrolet Bolt EV (VIN: [XXX] ) became completely immobilized on [XXX], due to high-voltage battery failure. The vehicle previously underwent all recall remedies, including a full propulsion battery replacement in May 2023, but less than two years later the same issue has reoccurred. This failure left us stranded and unable to operate the car. Loss of propulsion without warning presents a serious safety risk, particularly if it were to occur while driving at speed. Out of concern for fire risk, the dealer (Colonial Chevrolet in Milford, CT) parked the disabled vehicle approximately 500 feet away from other cars and structures. The dealer diagnosed the failure as HV battery pack malfunction and confirmed the pack requires replacement. The vehicle remains in their custody and is available for inspection upon request. GM Customer Assistance has denied two separate repurchase claims (case #[XXX] and #[XXX]), despite the prolonged immobilization and repeated delays. The car has been inspected by Colonial Chevrolet and GM representatives. Despite prior recall service and battery replacement, the Bolt is inoperable again, raising concerns that the recall remedy was ineffective and that other Bolt EV owners may face the same hazard. No warning lamps or error messages appeared prior to failure. The vehicle simply would not start on [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
